Ah, that sucks. I'll work on getting out a new version that allows you to
set the response timeout ASAP, to see if that will help. I'll let you know
once that's up.
In the meantime, if you get a chance to answer some of the questions below,
that'd be helpful in trying to track down if there's an issue beyond just
congestion causing the slow down.
* What's your environment like? Are the client and server talking over
localhost, or are they on different hosts?
* Is Ghidra under any load apart from the server script (e.g., is it
running analyses in the background)?
* How reliable is the timeout? Does it always happen, or does the script
sometimes succeed? Does it happen at the same point in the script or
different points? Does your script run okay for a while and then hit the
timeout?
Mostly trying to identify if this is more likely to be associated with a
particular type of command that's slow, or if I'm leading something that
causes the server to get progressively slower.

Hi,
Thanks for the update :-). Unfortunately now the pipe/socket does often
produce timeouts.
Appears to happen more often when some load is going through the
connection. (Maybe connected to the newly added threading)
tag 0.0.2 is still stable for me.

"Didn't receive response {} before timeout".format(response_id))
Exception: Didn't receive response 0a005460-93f5-46cd-8807-71f08280ebb6 before timeout
Thanks for updating it regulary :-) Helps a lot.
Cheers,
Traxes

I've just pushed version 0.0.4, which allows you to control the response timeout. I'd suggest trying something like GhidraBridge(namespace=globals(), response_timeout=2) and see if that helps any.
I'd be really keen to hear what length of timeout you finally need to avoid issues (especially if it doesn't stop the issues, or only delays them). And if you get a chance to look at the questions above while you're playing with that, that'd be really helpful.

Actually, if you haven't grabbed 0.0.4 already, please try 0.0.5 instead - all the response_timeout features, plus a couple of improvements/bugfixes which might also help.

No response, so I'll close this with the note that I've bumped the default response timeout up to 2 seconds.
